Description

Method for adjusting antenna communication and terminal equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for adjusting antenna communication and a terminal device.

Background

When the mobile terminal works, the working antenna arranged in a hand holding area can be attached tightly to influence communication, so that the switching of the working antenna is required according to the holding mode of a user, and the power gear of the working antenna is adjusted; in addition, in order to meet the standard of the electromagnetic Absorption Rate (SAR), the transmission power of the antenna needs to be adjusted according to different call holding scenes to ensure the communication quality.

In one mode, a proximity sensor is used to determine whether an object is approaching the mobile terminal product, and if an object is approaching the mobile terminal product, the antenna is backed-off after the object is approaching. In another mode, a conductive sheet (metal) is arranged on the back of the terminal mobile phone, a capacitance processor is connected with the conductive sheet, when a person holds the terminal, the conductive sheet respectively forms a capacitor in the person, and when the terminal is held by different holding gestures, capacitance difference of the capacitor is formed between the metal conductive sheet on the terminal and the person's hand to identify holding gesture of the left hand or the right hand.

However, the above two methods cannot accurately determine the holding scene, and firstly, the proximity light or the capacitive proximity sensor cannot determine whether an object is close to or a human body is close to, for example: when the mobile terminal is placed in a backpack or on a desktop, the backpack and the desktop can trigger the proximity sensor, and then an object is judged to be close to the mobile terminal; or other conductor contact terminals than a human hand may form a capacitor. Secondly, the user cannot be positioned in the accurate holding area, and the position relationship between the antenna and the hand cannot be positioned, so that whether the antenna is attached tightly cannot be judged. Finally, in the first mode, by "determining whether to approach", further adjusting the transmission power is not suitable for different SAR scenarios, such as: when holding a scene with one hand, although the human hand is close to the mobile terminal product, the top antenna is far away from the head and the trunk, theoretically, the antenna can transmit at a higher power, but because the scene cannot be identified, the lowest transmission power needs to be selected according to the strictest SAR scene, and the communication performance of the scenes is deteriorated. Therefore, a fine recognition of the holding scene and the call scene is required to further improve the communication performance under the holding of the human hand.

Disclosure of Invention

The embodiment of the application provides a method for adjusting antenna communication, and solves the problems of antenna power adjustment and antenna switching in different SAR scenes.

Detailed Description

The mobile terminal in the embodiment of the present application refers to a device with a touch display screen, and may include, for example, a mobile phone, a tablet computer, a personal computer, a workstation device, a large-screen device (e.g., a smart screen, a smart television, etc.), a handheld game machine, a home game machine, a virtual reality device, an augmented reality device, a mixed reality device, etc., a vehicle-mounted mobile terminal, an autonomous driving automobile, a Customer Premises Equipment (CPE), etc. It is understood that the mobile terminal also includes, but is not limited to, the following components: a Camera (Camera), a Receiver (Receiver), a Speaker (Speaker), a USB (USB), an Application Processor (AP), an embedded neural Network Processing Unit (NPU), and a Modem (Modem).

The touch display screen is an inductive liquid crystal display device capable of receiving input signals. The touch display screen and the chip thereof of the mobile terminal provided by the embodiment of the application can support the collection of full-screen hand textures, and the hand textures comprise: fingerprints and palm prints; further, the collection of full-screen hand veins can be supported, and the hand veins comprise: the veins and the palmar veins.

Fig. 1a is a schematic view of a scene where a person holds a mobile terminal in the left hand. As shown in FIG. 1a, when a user holds the mobile terminal, the pulp of the thumb, a part of palm under the thumb and the pulp of other fingers of the hand of the person are in contact with the touch display screen of the mobile terminal. In a specific embodiment provided by the present application, referring to fig. 1b, it can be seen that obtaining the fingerprint information of the contact position is to obtain the grip area. The chip of the touch display screen acquires hand textures on the touch display screen to obtain a holding area generated by hand contact, wherein the holding area is an area where the hand texture area is mapped to the touch display screen. Further, the area of the touch display screen is divided in advance to obtain the sub-area of the touch display screen, so that when a hand touches the local part around the touch display screen, the relation between the holding area and the sub-area can be obtained, and the holding positioning area of the hand is formed.

It is understood that other vital sign information can be obtained by the touch display screen, and obtaining vital sign information is equivalent to obtaining a grip area.

For example: the touch display screen can also acquire a vein of a hand, specifically, the touch display screen emits near infrared rays, the vein image on the touch display screen is acquired by utilizing the characteristic that human hemoglobin can absorb the infrared rays when passing through the vein, the vein image is processed to obtain a linear vein image, an extraction area is determined, a vein characteristic value of the area is extracted, second position information of the vein characteristic value is acquired, a holding area corresponding to the second position information is acquired, and the holding area is an area where the vein area of the hand is mapped to the touch display screen. Referring to fig. 1c, the images of the veins of the human hand are obtained by touching the display screen for collection, and then the holding area is obtained.

In the above, the human hand and the mobile device are in "area" contact, not point contact.

For another example: the touch display screen can also acquire surface acoustic waves of the touch display screen to obtain a holding area. Specifically, the method comprises the following steps: when a user touches the screen, the drag between the finger and the glass collides or rubs, and thus, sound waves are generated. The wave radiation leaves the contact point and is transmitted to the sensor, and an electric signal is generated according to the proportion of the sound wave; the position where the hand touches the screen can be located by analyzing the difference of these electrical signals. In addition, the touch display screen supports a surface acoustic wave recognition function, and the contact position of a finger on the screen is detected through the attenuation degree of the acoustic wave; when the touch screen is touched by a hand, sound waves are absorbed by fingers and are attenuated.

The following is a first embodiment of the present application that provides a method of adjusting antenna communications. The position mapping relation is established between the holding area and the touch display screen, so that the position relation between the antenna and the hand can be obtained by acquiring the mapping relation between the antenna and the touch display screen, and the power of the affected antenna is adjusted.

Fig. 2a is a system diagram of an antenna communication method according to an embodiment of the present application. As shown in fig. 2a, a touch display screen chip collects fingerprint information of a hand of a user to obtain a holding area; the antenna module obtains a mapping area of a target antenna by combining an antenna mapping table; the first processing unit obtains a first position relation between the target antenna and the hand according to the holding area and the mapping area; the second processing unit calls a first communication mode corresponding to the first position relation.

Fig. 2b is a flowchart illustrating a first embodiment of a method for adjusting antenna communication according to an embodiment of the present application. As shown in figure 2b of the drawings,

s1 collecting a holding area on the touch display screen;

in a specific implementation, referring to fig. 1a and 1b, it can be seen that a holding area refers to an area where a human hand texture area is mapped to a touch display screen.

In a specific implementation, referring to fig. 1a and 1c, it can be seen that the holding area refers to an area where a human hand vein area is mapped to the touch display screen.

In a specific embodiment, in order to regionalize the positioning of the hand holding area, the area of the touch display screen is divided in advance, and the obtained holding area is a sub-area of the touch display screen. Specifically, referring to fig. 3, the screen size of the mobile terminal is taken as a reference, and the screen is divided into 18 areas, which are from top to bottom and from left to right: region r, region c, region r

S2, acquiring a mapping area of the target antenna, wherein the mapping area is a sub-area where the setting position of the target antenna is mapped to the touch display screen;

as shown in fig. 4, when the fifth antenna disposed at the top of the mobile terminal is the target antenna, referring to fig. 3, the disposed region of the fifth antenna intersects with the region (i), the region (ii), and the region (iii), so that the mapping region of the fifth antenna is the region (i), the region (ii), and the region (iii). When the sixth antenna disposed on the left side of the mobile terminal is the target antenna, referring to fig. 3, the disposed area of the sixth antenna intersects with the area (r), so the mapping area of the sixth antenna is the area (r). The mapping areas of the other antennas are consistent with the confirmation method of the mapping areas of the fifth antenna and the sixth antenna, which is not described herein again.

S3, generating a first position relation according to the holding area and the mapping area, wherein the first position relation refers to the position relation between the target antenna and the human hand;

in the present embodiment, as the grip area shown at S1 and the mapping area shown at S2, the positional relationship (i.e., the first positional relationship) of the target antenna and the human hand is determined by whether or not the grip area and the mapping area intersect.

Taking the fifth antenna as the target antenna for example, the mapping areas of the fifth antenna are area (r), area (c) and area (c), and the holding area (including area (c), area (c)

) There is no intersection between them, i.e. the fifth antenna and the human hand are not in contact. Thus, the first positional relationship is a distant relationship, i.e., the human hand and the target antenna are not in contact.

S4, calling a first communication mode according to the first position relation;

the first positional relationship and the first communication mode are associated in advance, and different first positional relationships correspond to different first communication modes. The first positional relationship, that is, the positional relationship between the human hand and the target antenna obtained in the above-mentioned S3, includes a distant relationship and a close relationship; the first communication mode is to adjust a specific operation mode of the target antenna, and the operation mode specifically includes whether the target antenna continues to operate and an operation power of the target antenna.

In one specific implementation, the first communication mode does not set a maximum power back for the target antenna when the first positional relationship is a far relationship. When the first positional relationship is a close relationship, the first communication mode is to switch the antenna according to an antenna switching algorithm.

When the antenna switching algorithm selects the switched antenna, the antenna switching algorithm is based on the position relationship between the antenna and the human hand. Therefore, after the current working antenna is attached tightly and the transmitted signal is deteriorated, idle antennas (such as antennas with a position relation being a distant relation) arranged at other positions of the mobile terminal can be switched to carry out communication, and the influence of the scene that the antenna is attached tightly on the communication is solved.

Referring to fig. 1b and 4, in a specific embodiment, it can be determined that the fifth antenna and the sixth antenna are not touched by a human hand, and the first antenna, the second antenna, the third antenna, the fourth antenna, the seventh antenna, and the eighth antenna are attached by the human hand. Therefore, when the target antenna is one or more of the first antenna, the second antenna, the third antenna, the fourth antenna, the seventh antenna or the eighth antenna, the target antenna is switched to the fifth antenna or the sixth antenna.

In another specific embodiment, as shown in fig. 5, it can be determined that the first antenna and the second antenna are not contacted by the human hand, and the third antenna, the fourth antenna, the fifth antenna, the sixth antenna, the seventh antenna and the eighth antenna are attached by the human hand. Therefore, when the target antenna is one or more of the third antenna, the fourth antenna, the fifth antenna, the sixth antenna, the seventh antenna or the eighth antenna, the target antenna is switched to the first antenna or the second antenna.

Further, if the antenna set on the terminal equipment supports the TAS antenna switching algorithm, acquiring the transmitting power and the receiving power of the target antenna; and switching the idle antenna according to the transmitting power, the receiving power and the TAS antenna switching algorithm.

S5 adjusts the target antenna communication according to the first communication mode.

Referring to fig. 1b and fig. 4, taking the fifth antenna as the target antenna, the fifth antenna does not set the maximum power back.

As shown in fig. 5, taking the fifth antenna as the target antenna as an example, the fifth antenna is switched.

Referring to fig. 1a and 5, the same terminal device is held by hands, the holding gesture scene is also single left hand holding, fig. 1a is single left hand holding the lower half of the mobile terminal, and fig. 5 is single left hand holding the upper half of the mobile terminal. As can be seen from the figure, in fig. 1a, the antenna disposed at the top end of the mobile terminal is far away from the hand, and the antenna disposed at the bottom end is close to the hand; in contrast, in fig. 5, the antenna disposed at the top end of the mobile terminal is close to the hand, and the antenna disposed at the bottom end is far from the hand. It can be understood that when a user holds a mobile terminal product, the antenna arranged in the holding area is tightly attached, the transmission signal of the attached antenna is deteriorated, and different holding postures influence the antennas at different positions. Therefore, in order to improve the communication performance when held by a human hand, the communication mode of the fifth antenna is different between the two modes of "holding the lower half of the mobile terminal with a single left hand" and "holding the upper half of the mobile terminal with a single left hand",

according to the embodiment, the position relation between the antenna and the hand is obtained, so that the power of the affected antenna is adjusted, and the communication performance under the holding of the hand is improved. It is understood that, with the above-mentioned embodiments, under a certain holding scenario, the operation states of all the antennas (such as the first antenna, the second antenna, the third antenna, the fourth antenna, the fifth antenna, the sixth antenna, the seventh antenna, and the eighth antenna shown in fig. 4) provided on the device can be reset.

In the foregoing embodiment, in a specific implementation manner, the method for adjusting antenna communication further includes:

if the intersection of the mapping area and the holding area is an empty set, generating a first position result, wherein the first position result means that the target antenna is far away from the human hand; and calling a first sub-mode according to the first position result, wherein the first sub-mode is a sub-mode of the first communication mode.

In a specific embodiment, the first sub-mode refers to switching the target antenna according to an antenna switching algorithm, and the maximum power back of the target antenna is not set.

If the intersection of the mapping area and the holding area is a non-empty set, generating a second position result, wherein the second position result means that the target antenna is held by a human hand; and calling a second sub-mode according to the second position result, wherein the second sub-mode is a sub-mode of the first communication mode.

In a specific embodiment, the second sub-mode is to reduce the target antenna power back-off value XdB, and the OTA of the target antenna can be raised by XdB.

According to the implementation mode, the holding scene is identified finely, the corresponding communication sub-mode is called, and the communication performance under the condition of being held by hands is further improved.

In the above implementation, the intersection of the mapping region and the holding region is an empty set, and the antenna is not in contact with the human hand. However, the following scenario exists: the human hand abuts against the first section of the antenna or the human hand abuts against the tail end of the antenna, in which case the antenna communication is also affected and needs to be adjusted. Thus, the shortest distance between the mapping region and the holding region corresponding to the antenna far from the human hand is required to be greater than the first length threshold. The following description will be made by taking the holding posture shown in fig. 1b and 5 as an example:

referring to fig. 1b and 4, in a specific embodiment, it can be determined that the fifth antenna and the sixth antenna are not touched by a human hand, and the first antenna, the second antenna, the third antenna, the fourth antenna, the seventh antenna, and the eighth antenna are attached by the human hand. Then, an antenna, in this embodiment, a fifth antenna, is found, where the shortest distance between the antenna and the hand is greater than the first length threshold. Therefore, when the target antenna is one or more of the first antenna, the second antenna, the third antenna, the fourth antenna, the seventh antenna, or the eighth antenna, the target antenna is switched to the fifth antenna.

As shown in fig. 5, in another specific embodiment, it can be determined that the first antenna and the second antenna are not contacted by the human hand, and the third antenna, the fourth antenna, the fifth antenna, the sixth antenna, the seventh antenna and the eighth antenna are attached by the human hand; further, an antenna, in this embodiment, the first antenna, is found, where the shortest distance between the antenna and the hand is greater than the first length threshold. Therefore, when the target antenna is one or more of the third antenna, the fourth antenna, the fifth antenna, the sixth antenna, the seventh antenna, or the eighth antenna, the first antenna is switched.

The implementation mode realizes the selection of the optimal working antenna.

The following is a second embodiment of the present application that provides a method of adjusting antenna communications. Referring to fig. 1a and 6a, it can be known that different hands hold the mobile terminal, affecting antennas at different positions. The hand holding gesture scene of a hand held by a single left hand, a single right hand or both hands is identified, so that a communication mode corresponding to the hand holding gesture scene is called, and the power of the affected antenna is adjusted.

Fig. 7 is a flowchart illustrating a second embodiment of a method for adjusting antenna communication according to an embodiment of the present application. As shown in fig. 7, the method for adjusting antenna communication in this embodiment includes:

s101, recognizing a hand holding posture scene according to a holding area;

the hand holding posture scene comprises: held by a single left hand, a single right hand, or both hands.

In a specific implementation manner, the present application shows a method for identifying a hand-holding gesture scene by comparing a holding area with a preset area. Wherein the preset area is obtained by refining the key features. Specifically, as shown in fig. 1a, the holding posture of the human hand is left-handed holding, and feature information of the thumb, a part of the palm below the thumb, and other fingers of the human hand, which are in contact with the touch display screen, is acquired, where the feature information includes the contact area and the contact position of the human hand and the touch display screen, that is, when the left hand is held, the left side of the touch display screen is held by the thumb of the left hand, and the right side, the upper side, or the lower side of the touch display screen is held by the other fingers of the left hand, and the acquired feature information is imaged to obtain the first preset area. It will be appreciated that only representative characteristic information may be selected, such as: the characteristic information of the palm part under the thumb of the human hand contacted with the touch display screen and the characteristic information of the middle finger and the ring finger can be summarized in a partially refined mode.

On the premise of the implementation mode, the method for the hand holding posture scene is as follows:

and if the holding area is a first preset area, generating a first recognition result, wherein the first recognition result is held by a single left hand.

And if the holding area is a second preset area, generating a second recognition result, wherein the second recognition result is held by a single right hand.

Further, if the holding area is not the first preset area and not the second preset area, it may be determined whether the holding area is the third preset area. Further, it may also be directly determined whether the holding area is the second predetermined area.

The method for generating the third preset region is consistent with the first preset region, which is not described herein again.

The following describes an implementation manner of the third preset area provided in the embodiment of the present application with reference to the drawings.

Fig. 8a is a schematic view of a scene in which a user holds a mobile terminal in both hands. As shown in fig. 8a, when the user holds the mobile terminal with both hands, the mobile terminal is placed horizontally, a part of the palm under the thumb of the left hand and a part of the palm under the thumb of the right hand hold the same side of the mobile terminal at the same time, and the third preset area shown in the present application refines the key features accordingly.

It can be understood that the rotation of the screen can be determined by means of a gravity sensor and the like, and then relative position relationships such as "up", "down", "left" and "right" of the mobile terminal under the absolute position are obtained.

The implementation mode a: fig. 12a is a schematic structural diagram of a first embodiment of a third preset area in a method for recognizing a human hand holding gesture scene provided by the embodiment of the present application. As shown in fig. 12a, the mobile terminal is horizontally disposed, and the third preset area includes: the lower side of the touch display screen comprises at least two ninth areas 10 and the upper side of the touch display screen comprises at least two tenth areas 11. Further, two ninth areas 10 are respectively disposed at the lower left corner and the lower right corner of the touch display screen, and two tenth areas 11 are respectively disposed at both ends of the upper side of the touch display screen.

It can be understood that more fingerprint information is extracted as features, such as: the thumb appearing in the middle of the screen, the middle finger placed on the upper side of the mobile terminal and the like, so that the precision is more accurate.

If the intelligent equipment in the third preset area is vertically arranged, the implementation mode b of the third area is as follows: the lower side of the touch display screen comprises at least two ninth areas 10, the touch display screen comprises at least two tenth areas 11, the two tenth areas 11 are respectively positioned at two sides of the touch display screen, and the two tenth areas 11 are positioned at the upper sides of the two ninth areas 10. Further, as shown in fig. 12b, two ninth areas 10 are respectively disposed at the lower left corner and the lower right corner of the touch display screen.

It is to be understood that the determination methods and specific implementations of the first preset area, the second preset area and the third preset area are only used for explaining the embodiments of the present application, and are not intended to limit the present application.

When a receiver is in a conversation scene, the neck antenna of the mobile terminal is close to the Head, and the backspacing power is required to meet the Head SAR standard; and when the mobile terminal is not in a conversation scene, the mobile terminal is held by a single hand in a vertical screen mode, and the top antenna is far away from the head and the trunk, so that theoretically, the mobile terminal can be transmitted according to the maximum power without back-off. Therefore, whether the SAR system is in a call mode or not corresponds to different SAR scenes, and the different SAR scenes correspond to different SAR indexes.

Further, in a call scene, the SAR of the left head and the SAR of the right head are not consistent for the same antenna. Specifically, as shown in fig. 13a, when the mobile terminal is held by a single left hand to perform a call, the tenth antenna is close to the head, and the ninth antenna is far from the head relative to the tenth antenna; as shown in fig. 13b, when the mobile terminal is held by a single right hand for conversation, the ninth antenna is close to the head, and the tenth antenna is far away from the head relative to the ninth antenna. Referring to fig. 13a and 13b, it can be seen that the left head sar (leftheadsar) < right head sar (rightheadsar) of the ninth antenna; the right head SAR (rightHeadSAR) < left head SAR (leftHeadSAR) of the tenth antenna.

Therefore, the refined recognition holding scene and the call scene can adapt to different SAR scenes, so that the situation that the working antenna selects the lowest transmitting power according to the strictest SAR scene to cause communication deterioration in a non-call scene is avoided.

It is understood that the non-communication scenarios of the mobile terminal include: a single-hand-held internet surfing scene, a single-right-hand-held internet surfing scene, a double-hand-held game scene, a double-hand-held video watching scene and the like.

The third communication mode is a neck antenna proximate the head, backing off power.

And S1003, adjusting the target antenna communication according to the third communication mode.

As shown in fig. 13a, in a single-hand call scenario, the backoff of the ninth antenna is decreased, and the OTA of the ninth antenna may be raised:

as shown in fig. 13b, in the single-right hand-held call scenario, the tenth antenna backoff value is decreased, and the OTA of the tenth antenna may be raised.

It will be appreciated that the back-off value and the boost OTA value are determined by a pre-configured power gear table.

It can be understood that if the device is not in a call scenario, the antenna communication is adjusted according to the method for adjusting antenna communication shown in the foregoing first embodiment and second embodiment.

In addition, the method in the above embodiment may be referred to for determining the "hand holding posture scene", which is not described herein again.

As shown in fig. 15a, in a specific embodiment, the screen size of the mobile terminal is taken as a reference, such as a smart phone; the screen is divided into 18 areas according to the distribution of the antennas.
